Viggo Mortensen as Aragorn has very memorable facial hair in Peter Jackson's The Lord of the Rings film series. This stubble is one of his most defining physical attributes. And in his coronation scene in Return of the King, his beard is very mighty and full.

But it's not how Aragorn would look as described in the books, it seems. In the official lore, Aragorn does not have facial hair, and maybe not by choice. Some believe he cannot grow a beard, perhaps due to his Numenorean lineage and his Elvish ancestry. Aragorn's beard status been well-established already, but discussion picked up again this week thanks to a social media post.

Alex Perry on Twitter shared a wonderful story of a letter her mother received from JRR Tolkien himself about this. "I recently discovered that a fan letter my mum sent Tolkien when she was 15 is cited regularly in Tolkien scholarship, due to him answering her question about whether Aragorn canonically has a beard or not (he does not)," Perry wrote. "She believes he took the time to respond because she wrote to him in the Elvish language. I will never compete with her on being a gigantic nerd because that is truly world cup level."
